چکیده
In the title mol-ecule, C(18)H(15)NO(4), the benzoate ring is oriented at a dihedral angle of 43.43 (6)° with respect to the planar [maximum deviation = 0.038 (2) Å] chromene ring. The crystal structure features R(2) (2)(12) centrosymetric dimers formed via C-H⋯O inter-actions and these dimeric aggregates are connected by C-H⋯π inter-actions.
